MEANS FOR LOOKING WINDOW-SASHES TO SCREENS.

Specification of Letters Iatent.

Patented Aug. 20, 1918.

To all whom it may concern:

Be it known that we, LOUIS A. KLING and CHARLES F. DENNIS, citizens of the United States, and residents of East Cleveland, Ohio, and Cleveland, Ohio, respectively, have invented certain Improvements in Means for Looking Window Sashes to Screens, of which the following is a specification.

Our invention relates to certain improvements in car window frames in which a glazed sash is used and also a screen.

The object of our invention is to provide means for coupling the screen to the sash so that it can be raised with the sash to protect the window opening or, when desired, can be detached from the sash so as to allow a clear opening between the raised sash and the sill.

In the accompanying drawings:

Figure 1 is a View looking toward. the in side of a car window and illustrating the sash in the closed position;

Fig. 2 is an enlarged side view of the sash lock which secures the screen to the sash, the section being on the line 2--2, Fig. 3;

Fig. 3 is an end view of the lock shown in Fig. 2, the section being through the window frame; I

Fig. 4 is a section on the line 44, Fig. 3; and

Fig. 5 is a perspective view of the lock and a ortion of the. screen.

eferring to the drawings, 1 is the outside panel of the body of the car having'the inclined sill 2.. 3 is the inside panel having a sill 4. The two sills are spaced apart to allow a channel 5 for the passage of the screen 6. The screen is narrower than the channel so that it will have a certain amount of lateral movement in order to permit it to be coupled to or released from the sash. 7 is the glazed sash of the ordinary type adapted to rest on the inclined sill 2. At each side of the sash are locks 8, each consisting of a casing 9 secured to the sash and a latch lever 10 mounted on a pivot 11. Projecting at one side of the casing is a thumb hold 12, and one arm of the lever 13 is shaped so as to be engaged by the finger when it is desired to lift the lever. On the latch 10 is a projecting arm 14 which is arranged to engage the notches in the side walls of the frame in the ordinary manner so a to h ld he 2 1; in its raised position. In the bottom of the frame 9 of the lock is a T-shaped slot 15, the slot being wide near the sash and forming shoulders 16 on each side of the narrow por- 131011 17 of the slot. I At these shoulders are I'lbS 18 extending into the lock casing. On the upper edge of the frame of the screen 6 at each end thereof are T-headed projectlons 19 beveled at the back, as at 20. This T-headed projection is adapted to enter the slot l5 in the base of the lock casing. and can be lifted over the ribs 18 and into the narrow portion 17 of the slot so that when 1n this position, as illustrated in Figs. 2 and 3, the screen can be raised and lowered with the sash. In order to hold the screen frame to the sash, we provide an arm 21 forming part of the lever 10 and this arm is adapted to move in front of the T-head 19 when the hand. hold 13 is released by the hand, as illustrated in Fig. 2, so that when the sash is at rest the arm 21 will prevent the accidental displacement of the head 19. The

screen can be detached from the sash as soon as the lever 10 is moved to the position in which the arm 21 is clear of the head 19, as in Fig. 5.

It will be noticed that the arm is notched at 22 so as to partly extend over the end of the head 19', holding it in position back of the ribs 18, thus preventing it from being ralsed or moved outward. Any suitable means'may be provided for lifting the screen into engagement with the sash lock and moving it laterally so that the T-head 19 will pass over the 'ribs 18. Suflicient clearance is allowed in the channel 5, in which the screen frame 6 is located, to allow for this lateral movement.

By the above construction, we provide a simple and effective means for detachably looking a screen frame toa sash. Thelockin means also acts to hold the sash in itshold the sash in its raised position; means for detachab'ly connecting the screen to the sash lock; and a lever having an arm ar ranged to lock the screen to the sash.

2. The combination of a Window frame; a sash; a screen, said frame having a channel adapted to receive the screen; a sash lock secured to the sash, said lock having a T-slot and an internal rib at the T-slot, the screen frame having a T-headed projection adapoted to enter the slot and'to pass over the ri so as to attach the screen to the sash.

' 3. The combinationof a window frame; a sash; a screen; said frame having a channel adapted to receive the screen; a sashlocli' secured to the sash, said lock having a T-slot and aninternal rib at the T-slot, the screen frame having a T-headed projection adapted to enter the slot and to pass over the rib so as to attach the screen to the sash; a locking lever having an arm located in front of the T-headed projection on the screen when in the normal position and, when raised, to

newer/e of the sash, each lock having a pivoted latch 30 provided with an arm arranged to engage the Window frame to hold the sash in the raised position; a T-headed slot in the bot tom of the lock; an internal rib at the junction of the narrow and the wide portion of 3 the slot, said rib. extending into the casing; and a T-headed projection at each end of the screen adapted to enter the slot and to pass over the rib, the lever having a notched arm arranged to engage the T-headed projection on the screen when the lever is in its normal position, preventing the screen being detached from the sash untilithe lever is raised.
